GLENDALE, Ariz. (AP) Arizona quarterback Carson Palmer has left the Cardinals' game against the Los Angeles Rams to be evaluated for a concussion.
Palmer went out late in the fourth quarter after a sack by Aaron Donald rattled his head around. Palmer had trouble getting up and appeared to be woozy as he left the field.
He was checked out on the sideline and later walked to the locker room to be evaluated. Palmer was replaced by Drew Stanton after throwing for 288 yards with a touchdown and an interception on 23-of-36 passing.
